Water Change And Still Nothing

I am stuck on fish in cycle and had 0.25 ammonia done a 50% water change and uts still the same

Then you need to do another one. If it was truly 0.25ppm, a 50% change will still leave you with 0.125 ppm. This is better, but still too high to register yellow, if you're using the API liquid test kit.

Try looking at the test tube under natural light, or fluorescents. Mowbz had an issue a few months ago, where he thought he had 0.25ppm ammonia, stripped the tank to bits, then looked at the test again under different lights, and saw it was 0.

I agree, whenever I test my tank water under artificial light it looks like 0.25ppm. But in natural daylight it is 0ppm. When this first happened it caused me to do a massive water change that wasnt actualy needed.

I agree with Tom. Natural light can make a big difference. I've also found that most incandescent bulbs can better simulate this natural light effect despite our feeling that they can give a room a warmer effect. So many of us now have compact fluorescents of various types - many of these are the ones that will give the 0.25 effect.

I suppose the other thing to check once the lighting has been resolved is the source water. Sometimes tap water comes in with enough ammonia to be detected by our kits.
